The drive (1) has a gear wheel with an internal thread by which the gear wheel is rotatably supported at an external thread (21) of a guide cylinder (20) so that the gear wheel is movable during a rotation along a cylinder axis (22) of the guide cylinder. A linear guide (80) is provided for guiding a housing (50), which runs at a distance parallel to cylinder axis. The linear guide stands in contact with the housing so that movement of the housing against the linear guide in radial direction to the cylinder axis is prevented. An independent claim is also included for a coffee brewing device with a damping element. |
